Acer aspire one; During start up (with a battery installed), the computer defaults to a blank screen and then produces a continues tone. If only the charger cable is attached without the battery the computer starts fine. I have tried a second battery with the same result so its not the battery.
More aboutacer aspire steady tone start
i would guess there is a solder point or capacitor some ware between the battery and the MB that is busted and is causing a POST error.... my dell latitude did that so now its just a mini desktop
